ControlPaint.DrawScrollButton - need this to work with visaul styles

Hi,

I'm overriding the DateTimePicker to add some features, this involves me manually drawing the control.

When I initially draw, it displays fine, I'm using

ControlPaint.DrawScrollButton (for the drop-down on the right)
and
ControlPaint.DrawCheckBox (if it has the ShowCheckBox property set)

It draws the scroll button on the right (the drop-down), in the default style, but when I click on the drop-down, the control itself draws the 3d version (coming from windows themes).

Is there a way of either drawing the ScrollButton in 3d, or disabling the automatic drawing of the button when clicked ?

Cheers
Smg.

No, my problem is that my application already draws using visual styles (I have the above statement in my application), but when I draw it manually using

ControlPaint.DrawScrollButton

It draws the scrollbutton without using visual styles... but then when I dropdown, it draws over the top of it with the 3d version... this doesn't look very professional.

Even though I'm 'owner-drawing' tihs control, the 'scrollbutton' is being drawn by the control, not by my inherited version. It only draws this when I click on the drop-down. I guess this is because the calendar that appears is a separate hWnd, and for some reason it draws the 'drop-down/scroll button'

Hi.
If you using .NET 1.0/1.1 this is possible to use uxTheme.dll. See pinvokes from http://pinvoke.net/default.aspx/uxtheme.DrawThemeBackground site.

If your program compiled under .NET 2.0 you can use classes from System.Windows.Forms.VisualStyles namespace.

Try something like this:
Graphics graphicsWhereToDraw = ...;
VisualStyleRenderer renderer =
                new VisualStyleRenderer(VisualStyleElement.ScrollBar.ArrowButton.DownDisabled);
renderer.DrawBackground(graphicsWhereToDraw, new Rectangle(0, 0, 10, 10));
// done

Open in new window
